I know infinitely more football than you. There was an easy 30 points out there last night. The Rams defense isn't special at all.
Dak was horrendous. He just can't pull the trigger when it's not a designed throw. He looks at one guy, then dumps down if he doesn't like it. He can throw the deep sideline route because it requires no thought. But windows over the middle that aren't his first read are almost impossible. He doesn't have the confidence to do it unless guys are running free, so he pulls the ball down, gets Fred Flintstone feet, and takes the sack. And in the red zone, he may be one of the worst QBs in the NFL.
They call a dumbed-down offense for him for a reason. Romo didn't run this high school offense. McCarthy uses far more intricate plays than what you saw last night. I think Moore told McCarthy basically "look, this is what he can do", so McCarthy is letting him call the plays right now.
Dak could not dream of running the offense Farve and Rodgers did, so McCarthy is taking a back seat. FOR NOW.
I hope he finds a rhythm, but last night was the same old Dak. When the other team stinks or is not into it, he can shine, but when the Cowboys need him to carry them, he just can't.
